Is It Safe for Dogs to Eat Crab Shells?

Feeding crab shells to dogs is a topic that requires careful consideration, as it comes with potential risks and benefits. While dogs are naturally curious and may be drawn to the aroma and texture of crab shells, there are several factors to keep in mind before allowing your furry friend to indulge in this seafood treat.



Potential Health Benefits of Crab Shells

Crab shells, while posing potential risks to dogs, also offer some potential benefits that might be worth considering. These benefits are primarily associated with the presence of chitin, a fibrous substance found in crab shells.

Here are some potential advantages of feeding crab shells:

  • Chitin for Joint Health:

Chitin is known for its potential benefits in supporting joint health. It is often used in dietary supplements and medications intended to promote healthy joints and cartilage in both humans and animals.

Including crab shells in your dog’s diet could introduce chitin, which may help maintain the structural integrity of joints and connective tissues.

  • Connective Tissue Support:

The chitin in crab shells may contribute to the overall health of connective tissues, which include tendons, ligaments, and cartilage. This could be particularly beneficial for active dogs or those with joint concerns, as it may help maintain their mobility and flexibility.

  • Digestive Aid:

Some proponents suggest that the chitin in crab shells could aid in digestion. While more research is needed in this area, the fibrous nature of chitin might potentially assist in regulating digestive processes and promoting gastrointestinal health.

  • Dental Stimulation:

The act of chewing on crab shells could provide dogs with natural dental stimulation. The abrasive texture of the shells may help remove plaque and tartar buildup from teeth, contributing to better oral hygiene and potentially reducing the risk of dental issues.

Risks and Considerations

When it comes to feeding crab shells to dogs, there are several important risks and considerations that every responsible pet owner should be aware of.  Here are the key risks and considerations associated with giving crab shells to dogs:

  • Choking Hazard:

Crab shells can easily splinter into sharp fragments, presenting a serious choking hazard for dogs. If a dog ingests these sharp pieces, it could lead to blockages, internal injuries, or even life-threatening situations.

  • Digestive Issues:

Dogs’ digestive systems are not adapted to process crab shells efficiently. Ingesting large quantities of shell material may lead to gastrointestinal distress, including vomiting, diarrhea, and stomach upset.

  • Allergic Reactions:

Introducing new foods, especially novel proteins like crab, can potentially trigger allergic reactions in some dogs. Allergies can manifest as skin problems, itching, digestive issues, or more severe symptoms.

  • Salt Intake:

Crab shells often contain a notable amount of salt. Excessive salt intake can be harmful to dogs and may lead to sodium ion poisoning, causing symptoms like vomiting, diarrhea, increased thirst, and even seizures.

  • Bacterial Contamination:

Seafood, including crabs, can carry harmful bacteria and parasites. Raw or undercooked crab shells can increase the risk of bacterial contamination, potentially causing food poisoning in dogs.

Raw Crab Shell VS Cooked Crab Shell

Certainly, here are the potential pros and cons of feeding raw crab shells and cooked crab shells to dogs:

Raw Crab Shell:


  • Raw crab shells contain minerals such as calcium and phosphorus, which are important for bone health and overall growth in dogs.


  • Raw crab shells are tough and difficult to digest, potentially causing gastrointestinal problems or blockages.
  • The shells can be a choking hazard or may cause injury if they splinter or break.
  • Even if the shells don’t splinter, they can break into sharp fragments that could damage a dog’s digestive tract.
  • Dogs can be allergic to shellfish, and feeding them raw crab shells increases the risk of allergic reactions.


Cooked Crab Shell:


  • Similar to raw shells, cooked crab shells can provide some minerals, although cooking may alter their nutritional composition.
  • Cooking crab shells can release fragrant aromas and flavors that could potentially enhance a dog’s interest in their food.


  • Cooked crab shells, while more brittle, are still not easily digestible and could lead to gastrointestinal issues.
  • Cooked shells are more likely to splinter, creating a higher risk of choking or injury.
  • If the crab shells were cooked with salt or seasonings, they could be harmful to dogs due to their sensitivity to sodium.


In summary, both raw and cooked crab shells come with significant risks and potential harm to dogs. It’s best to avoid feeding crab shells altogether and instead focus on providing your dog with safe and nutritious options.

If you want to introduce crab meat into your dog’s diet, it’s crucial to cook the meat thoroughly, remove all shells, and consult your veterinarian for guidance.

Conclusion-Can Dogs Eat Crab shell?

Dogs should not be given crab shells to eat. Both raw and cooked crab shells can present significant risks to a dog’s health.

The tough and hard texture of crab shells makes them difficult for dogs to digest, potentially leading to gastrointestinal issues, discomfort, or blockages.

Moreover, crab shells can splinter into sharp pieces, creating a choking hazard or causing internal injuries to a dog’s mouth, throat, upset stomach or digestive system. Even if the shells don’t splinter, they can break into smaller fragments that might be hard to pass through the digestive tract.

Furthermore, crab shells are not a natural part of a dog’s diet, and their consumption does not offer substantial nutritional benefits. While crab meat itself can provide some protein and nutrients, it should be properly cooked and free from shells, which should be completely removed before offering the meat to a dog.

The risks associated with feeding crab shells to dogs far outweigh any potential benefits, making it essential to prioritize their safety and well-being by avoiding the inclusion of crab shells in their diet.

If you’re considering introducing new foods to your dog’s diet, it’s advisable to consult a veterinarian for guidance and recommendations based on your dog’s specific dietary requirements and health considerations.
